Hosts in the CS Student Computing Environment


CS course work should be done on CS hosts, preferably the standard environment Linux and Windows servers or the Mac lab workstations, unless otherwise indicated by the course instructor. CS students also have access to hosts in the Math Student Computing Environment.

While CSCF tries to make the same versions of software and specific functionality available across all student computing servers and workstations, there are unavoidable differences among environments.

You can login directly to the teaching environment:

Ubuntu Linux systems
using "ssh -Y linux.student.cs.uwaterloo.ca" from anywhere.
Windows 2008 systems
using RDP connection such as "rdesktop windows.student.cs.uwaterloo.ca" from machines on UW's main campus.
Apple iMac workstations
do not permit remote access.

Hosts named with the "mef-" prefix were made possible with help from the Math Endowment Fund.

Current Recommended Computing Environments

The standard environment servers are recommended for general course work. Software on these servers is kept up to date between terms, with minimal changes between the first day of lectures and the last day of exams in any given term. Significant changes in this environment, such as an OS version/distribution change, tend to occur between the end of the Winter term and the beginning of the Spring term.

Linux

linux.student.cs.uwaterloo.ca or ubuntu.student.cs.uwaterloo.ca are the generic names to select the current recommended Linux version. Currently this is:

ubuntu-1604.student.cs.uwaterloo.ca
which provides load-balancing redirection to one of these hosts:
 Hostname CPU Type # of CPUs Cores/CPU Threads/Core RAM (GB) Make Model
 ubuntu1604-002.student.cs.uwaterloo.ca   Intel Xeon E5-2697 v3 2 14 2 256 Dell R730
 ubuntu1604-004.student.cs.uwaterloo.ca   Intel Xeon Gold 6148 2 20 2 384 Supermicro 6029P
 ubuntu1604-006.student.cs.uwaterloo.ca   Intel Xeon E5-2697A v4 2 16 2 256 Dell R730
 ubuntu1604-008.student.cs.uwaterloo.ca   Intel Xeon E5-2697A v4 2 16 2 256 Dell R730

If you have problems accessing these Linux servers from a thin-client or nettop lab, please refer to this FAQ information on how to restore a known working GUI setup.

For general login problems, which would also affect Windows and Mac access, you may need to reset your CS password.

Macs

These labs are available as long as the room is not booked (e.g. for a lab, a summer camp, or a conference). All Math faculty undergraduate students, whether they are registered in CS courses or not, are permitted to use the Mac labs.

Please observe the protocol in the Lab Bookings Section of CSCF Policy for Teaching Labs.

The Mac labs are:
 Room Seats CPU RAM (GB) Model Screen
 MC2062 30    Intel Core i7-2600S Quad Core 2.8GHz 16 21.5" Mid-2011 iMac    Built-in 21.5" 1080p 60Hz
 MC2063 30    Intel Core i7-2600S Quad Core 2.8GHz 16 21.5" Mid-2011 iMac    Built-in 21.5" 1080p 60Hz
 MC3003 67    Intel Core i7-4579U Dual Core 3.0GHz 16 Late 2014 Mac Mini    ASUS PB287Q 28" 4k 30Hz
 MC3004 31    Intel Core i7-3720QM Quad Core 2.6GHz 16 Late 2012 Mac Mini    ASUS PB278Q 27" 1440p 60Hz
 MC3005 32    Intel Core i7-4579U Dual Core 3.0GHz 16 Late 2014 Mac Mini    ASUS PB287Q 28" 4k 30Hz
 MC3027 32    Intel Core i7-3720QM Quad Core 2.6GHz 16 Late 2012 Mac Mini    ASUS PB278Q 27" 1440p 60Hz
Windows

Use one of the Eon thin clients or an RDP client (e.g. rdesktop on any of the NetTops or iMacs) to either of the above generic names and it will use Microsoft network load balancing to one of these Windows 2008 Terminal Server systems:

windows.student.cs.uwaterloo.ca (also known as elegans.uwaterloo.ca)
Hostname CPU Type # of Cores RAM (GB) Make Model
windows08.student.cs.uwaterloo.ca AMD Opteron 4 8 Oracle Sun Fire x4200
windows10.student.cs.uwaterloo.ca AMD Opteron 4 8 Oracle Sun Fire x4200
Utility Computing

CSCF provides a reconfigurable computing resource to augment course and student requirements. There are currently 28 client nodes: 16 Sun X2100s with 1 CPU, 1GB memory, and an 80GB hard drive; 7 Sun X2200s with 2xquad AMD CPU's, 8GB memory, and a 240GB hard drive (2 machines have 500GB hard drives); and 5 Dell R415s, 4GB RAM, AMD 4122, 4 core 2.2GHz 75watt, 250GB SATA drive. There is also 1 Sun X2200 (head node) with 2xquad AMD CPU's, 16GB memory, and a 240GB hard drive. Seven of the nodes also contain DVD drives.

The current nodes are named:

  • ugster01.student.cs.uwaterloo.ca - ugster28.student.cs.uwaterloo.ca

Past examples of use are as a Rocks compute cluster running CentOS (a derivative of Redhat Linux), and as ten pairs of performance analysis nodes running Ubuntu Linux. Use is specific to undergraduate courses requiring clustered computing (e.g. CS457). The "ugster" machines are not intended for general login.

Services Hosts

Service Hosts run as virtual machines within the SCS private cloud. They are dedicated for specific tasks such as ACM International Collegiate Programming Contest team pratices and local events, Electronic assignment handling (marking), Course and student web services (HTTP and related protocols), Database servers, Other dedicated Course use, Printing, sftp, version control, CIFS.

Previous Computing Environments

If your instructor gives permission or tells you to use them, the previous environment servers are available for course work . Software on these servers was supported by CSCF as the default up to the previous April; (other than for security reasons) software updates are generally unavailable for these servers.

ubuntu1404.student.cs.uwaterloo.ca is the load-balanced name to select one of these Linux Ubuntu 14.04 systems:

ubuntu-1404.student.cs.uwaterloo.ca
which provides load-balancing redirection to one of these hosts:
 Hostname CPU Type # of CPUs Cores/CPU RAM (GB) Make Model
 ubuntu1404-002.student.cs.uwaterloo.ca   AMD 6100 4 12 128 Dell R815
 ubuntu1404-004.student.cs.uwaterloo.ca   AMD 6300 4 16 256 Dell R815
 ubuntu1404-006.student.cs.uwaterloo.ca   AMD 6100 4 12 128 Dell R815
